Files to help bootstrap PySide6 with an event loop within Blender.

BQt

Add QT support to Blender, letting you create custom UI for your addons with PySide6 QtWidgets.

Features

feature	description
fully custom UI	Instead of feeling limited by N-Panel only UI. Do whatever you want.
cross app	Qt widgets run natively in Krita, 3ds Max, Maya, … and are great to use in cross dcc pipelines
existing community	hundreds of QT widgets on GitHub you can reuse, and lots of stack exchange questions answered regarding qt.
Themed	BQt applies the blender-qt-stylesheet so qt widgets will by default look similar to Blender.

Requirements

• Blender 4.2 (bqt aim to support the earliest LTS version still under support)
• Windows or Mac
• PySide6
• PyObjC & iterm2 (Mac only)

How to use

1. Install & enable the bqt addon (see installation docs)
2. Create & show your Qt widget, bqt will automatically register it with its widget manager.

• sample code: bqt_demo shows you how to use bqt with several qt demos you can run in Blender
